Sirius, Remus, and Peter sat in silence. McGonagall headed up to the girl's dormitory again, this time to retrieve Snape. She walked in and he was lying on the floor. She gave him a vicious glare and noticed that with his arms at his sides, she could not tie his hand together so that he could be led to Dumbledore's office. The only option was to unpetrify him and then bind him. She raised her wand and muttered the anti-charm.

She was about to use her wand to bind him when from under him, Snape pulled out his wand and petrified her! McGonagall went wide-eyed and hit the ground. Snape walked to her and picked up her wand.

Now to get out of here... he thought. He opened the door and walked to the bottom of the staircase, hiding in the shadows. He had a clear view of his enemies from there, and they were oblivious to the world.

Snape grinned and whispered under his breath. He ran out from where he hid.

Sirius and Remus reached for their wands as Snape suddenly appeared from the staircase. Peter also fumbled for his, but he dropped it and it rolled under the couch. He jumped down and crawled under it to retrieve it. Snape suddenly yelled, PERFECTUS TOTALIS! and used both wands to take Sirius and Remus down before they had a chance. They hit the floor with two sickening thuds, and Peter scrambled to retrieve his wand. Snape ran out of the Common Room, and from there he started to run down the long chain of stairs in the castle.
